'The Voice' Reignited Gwen Stefani's Love For Music

Gwen's having fun and being inspried on 'The Voice.'

Gwen Stefani is back in the studio, and she's "killing it," according to Pharrell, and for that, you can thank "The Voice."

The "Hollaback Girl" will officially take her seat as coach, along with Pharrell, Blake Shelton and Adam Levine, as the hit singing show kicks off its seventh season on Monday (September 22).

According to the pop star, her "Voice" gig was completely "unexpected," and she tells us that the show has her falling in love with music all over again.

"It really reignited so much music in me because wearing the hat of a coach and being around so much music and being around the other coaches and just seeing people perform, there's no way for that not to be inspiring and effect me in a way I didn't even really know that it was going to do that," Gwen said. "I wasn't even thinking that deep about it, so it's been great. It taught me a lot."

"The Voice" was just what she needed to give her that little push to get back in the studio, where she is working on both a No Doubt album and a solo album with Pharrell.

"At this point in my life, I need things to shake me up," she said about wanting to be challenged. "I can go in and sit and knock my head against the wall trying to write a song or I can be really inspired and go in and write a song. So it was a difference, so I feel like it's been really inspiring."

Gwen's husband Gavin Rossdale makes an appearance on the show as a guest mentor, and while "The Voice" itself hasn't been a challenge to Stefani, it has been hard juggling her family life.

"Just maybe the hours and having the children -- that part of it. But that part is always challenging no matter what," she said. "But being on the show has not been challenging, it's been so fun."
